Chemistry part 2
Carbon dioxide and water are NOT on the periodic table. this is because they are ------- not elements
compounds
Length of pencil in cm (I will give you the pencil)
18 cm
Mr. Howe will describe a smart pill experiment. What is the independent variable in this experiment?
Pill type (smart pill or none)
"heat transfer is really neat, it always goes from --- to ---
hot to cold
see the board:
A is pointing at what?
amplitude of the wave (height)
An element that has similar properties to Sodium (Na) is
Potassium (K) or anything underneath it
Look at board--if the field of view diameter is 3 mm, how large is the cell in this field of view?
1mm (3 fit across the field of view so 3mm/3=1mm
make a hypothesis about this smart pill experiment
I predict that.......will.......
solid substances transferring heat to other solid substances
conduction
B is pointing at what
the wavelength
columns on the periodic table are called
groups
2 mistakes with the graph on the board
inconsistent scale on y-axis
y-axis not labeled
origin not labeled on either axis
2 things that should have remained constant in the smart pill experiment
DAILY DOUBLE!!!!!!!!!!!!!!!
age, ability level, same test, same time of day, same amount of sleep and health, etc.
heat transfer in a liquid or in the atmosphere
convection
We see ourselves in a mirror because of what property of light?
reflection
smallest particle of an element is called:
All matter in the universe made of these
atoms
Which variable goes on which axis
independent on x-axis
dependent on y-axis
Dependent variable in the smart pill experiment
test scores
The particles in the metal move faster and move further apart
A pencil put in a cup of water appears to bend when you look through the cup. Which property of light is this?
refraction
2 or more substances combined physically together, but not making a chemical reaction. For example, salt water.
mixture
Make a scale for this data and graph it (line graph)
Days: Height:
1 20 cm
2 40 cm
3 50 cm
4 60 cm
5 100 cm
draw on board
Group that did get the pill is called the experimental group. Group that didn't get the pill is called----
the control group
"The average kinetic energy of a substance" is better known as what
temperature
The amount of waves that pass through a fixed space at one time is called
frequency
